- ItemAn algorithm for generalised convex quadratic programming : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at Massey University(Massey University, 1965) Evans, David AnthonyThe purpose of this thesis is to review work carried out by Professor W. V. Candler of the Department of Agricultural Economics and Farm Management at Massey University, leading to the development of a Generalised Convex Quadratic Programming Algorithm. However the responsibility for the following manner of presenting the material and forming the arguments rests with the candidate. The first chapter gives a brief summary of the algebra of quadratic functions which will form a background for future developments. At the end of Chapter 1 is a bibliography for further and more detailed reading. Chapter 2 classifies the problem in the title within the frame-work of the more general mathematical programming problem. Chapter 3 describes and developes the mathematical conditions which any successful algorithm must satisfy, and Chapter 4 developes the algorithm, in the form of three separate algorithms, as a form of presentation. The last chapter provides a brief discussion.
- ItemGenetic studies of a darkening of the dorsal coat in agouti mice : a thesis ... for the degree of Master of Agricultural Science(Massey University, 1962) Evans, David AnthonyIt is the candidate's contention that an understanding of the mechanisms of gene action and interaction at the physiological level, is a necessary basis for a fuller understanding of the principles and problems of animal breeding. On this point, Rae (1958) states ... "population genetics deals essentially with genes and final phenotypes, but has little to say about the vast developmental gap between the two". However, opportunities for physiological studies of simple Mendelian traits in farm livestock are few and far between, while the expense of such studies is normally prohibitive. Consequently, physiological genetic studies are normally carried out on small animals, especially the mouse. Gruneburg (1952) has reviewed the use that has been made of this mammal for genetic studies of all types. [FROM INTRODUCTION]
